GREEN BAY - A 21-year-old from Pound was bound over for trial in the shooting death of a Preble High School student after waiving his preliminary hearing Thursday in Brown County Circuit Court.

Jared C. Williquette is charged with party to the crime of first-degree reckless homicide in the shooting death of 18-year-old Federico Abarca of Green Bay. According to the Green Bay Police Department, Williquette shot Abarca in the chest Feb. 22 during an attempted robbery that was set up as a drug sale.

Three others who were involved in the robbery scheme, Gavin M. Rock, 17, and Colton G. Kehoe, 18, both of De Pere, and Jarid W. Stevens, 20, Oconto, have also been charged with reckless homicide in connection to Abarca's death.

Williquette, Rock, Kehoe and Stevens are are also charged with conspiracy to commit robbery and conspiring to obstruct a police investigation. Rock and Williquette are also charged with bail jumping.

A number of Abarca's family and friends were in the courtroom for the hearing.

Police say the four decided to rob Abarca of four THC cartridges, which they referred to as "dabs."

THC cartridges, 'dabs' explained

Aaron Beck a patient consultant at Glendale GreenHouse in Glendale, Arizona, explained the difference between the dabs and THC cartridges.

Dabs are made by using a solvent to extract concentrated THC from marijuana,Beck said. Once the extract is purged of the solvent, the result can resemble brittle glass, a honeycomb or wet sugar granules.

“It's basically like today’s version of hash. Like more potent because it's been refined through a chemical extraction,” Beck said.

As for THC cartridges, the marijuana undergoes an extraction process but the oil that results is put into a cartridge and smoked in a device similar to an e-cigarette, he said. Dabs are generally more potent than the cartridges.

While marijuana is legal in other states, it is still illegal in Wisconsin, said Green Bay Police Lt. Rick Belanger.

Locally, and statewide, law enforcement officials are more frequently seeing dabs and cartridges, Belanger said, though that doesn't mean officers are seeing less marijuana.

Drug field tests are capable of detecting THC in a lot of cases, and police dogs are still able to find THC derivatives.

Court hearings

Williquette appeared in court with his attorney, Alf Langan, who told Court Commissioner Chad Resar that there have been discussions with prosecutors about a possible plea agreement, but those takes have not resulted in anything "concrete."

Williquette is scheduled to be arraigned April 8.

The balance of initial appearances are scheduled for March 20 for Rock, Stevens and Kehoe.
